Generally, a quitclaim is a formal renunciation of a legal claim against some other person, or of a right to land. A person who quitclaims renounces or relinquishes a claim to some legal right, or transfers a legal interest in land. Originally a common law concept dating back to Medieval England, the expression is in modern times mostly restricted to North American law, where it often refers specifically to a transfer of ownership or some other interest in real property.
